  compression ratio on some files. This also allows inlining _tr_tally for
  matches in deflate_slow.

ZLIB DATA COMPRESSION LIBRARY

zlib 1.2.11 is a general purpose data compression library.  All the code is
zlib 1.2.13 is a general purpose data compression library.  All the code is
thread safe.  The data format used by the zlib library is described by RFCs
(Request for Comments) 1950 to 1952 in the files
http://tools.ietf.org/html/rfc1950 (zlib format), rfc1951 (deflate format) and
rfc1952 (gzip format).

All functions of the compression library are documented in the file zlib.h
(volunteer to write man pages welcome, contact [email protected]).  A usage example

PLEASE read the zlib FAQ http://zlib.net/zlib_faq.html before asking for help.

Mark Nelson <[email protected]> wrote an article about zlib for the Jan.  1997
issue of Dr.  Dobb's Journal; a copy of the article is available at
http://marknelson.us/1997/01/01/zlib-engine/ .

The changes made in version 1.2.11 are documented in the file ChangeLog.
The changes made in version 1.2.13 are documented in the file ChangeLog.

Unsupported third party contributions are provided in directory contrib/ .

zlib is available in Java using the java.util.zip package, documented at
http://java.sun.com/developer/technicalArticles/Programming/compression/ .

  The deflate format used by zlib was defined by Phil Katz.  The deflate and
  zlib specifications were written by L.  Peter Deutsch.  Thanks to all the
  people who reported problems and suggested various improvements in zlib; they
  are too numerous to cite here.

This is a patched version of zlib, modified to use
Pentium-Pro-optimized assembly code in the deflation algorithm. The
files changed/added by this patch are:

README.686
match.S

The speedup that this patch provides varies, depending on whether the
compiler used to build the original version of zlib falls afoul of the
PPro's speed traps. My own tests show a speedup of around 10-20% at
the default compression level, and 20-30% using -9, against a version
compiled using gcc 2.7.2.3. Your mileage may vary.

Note that this code has been tailored for the PPro/PII in particular,
and will not perform particuarly well on a Pentium.

If you are using an assembler other than GNU as, you will have to
translate match.S to use your assembler's syntax. (Have fun.)

Added for zlib 1.1.3:

The patches come from
http://www.muppetlabs.com/~breadbox/software/assembly.html

To compile zlib with this asm file, copy match.S to the zlib directory
then do:

CFLAGS="-O3 -DASMV" ./configure
make OBJA=match.o


Update:

I've been ignoring these assembly routines for years, believing that
gcc's generated code had caught up with it sometime around gcc 2.95
and the major rearchitecting of the Pentium 4. However, I recently
learned that, despite what I believed, this code still has some life
in it. On the Pentium 4 and AMD64 chips, it continues to run about 8%
faster than the code produced by gcc 4.1.

In acknowledgement of its continuing usefulness, I've altered the
license to match that of the rest of zlib. Share and Enjoy!

/* Maximum size of the dynamic table.  The maximum number of code structures is
   1446, which is the sum of 852 for literal/length codes and 594 for distance
   codes.  These values were found by exhaustive searches using the program
   examples/enough.c found in the zlib distribtution.  The arguments to that
   examples/enough.c found in the zlib distribution.  The arguments to that
   program are the number of symbols, the initial root table size, and the
   maximum bit length of a code.  "enough 286 9 15" for literal/length codes
   returns returns 852, and "enough 32 6 15" for distance codes returns 594.
   The initial root table size (9 or 6) is found in the fifth argument of the
   inflate_table() calls in infback9.c.  If the root table size is changed,
   then these maximum sizes would be need to be recalculated and updated. */

/*
 * inffast.S is a hand tuned assembler version of:
 *
 * inffast.c -- fast decoding
 * Copyright (C) 1995-2003 Mark Adler
 * For conditions of distribution and use, see copyright notice in zlib.h
 *
 * Copyright (C) 2003 Chris Anderson <[email protected]>
 * Please use the copyright conditions above.
 *
 * This version (Jan-23-2003) of inflate_fast was coded and tested under
 * GNU/Linux on a pentium 3, using the gcc-3.2 compiler distribution.  On that
 * machine, I found that gzip style archives decompressed about 20% faster than
 * the gcc-3.2 -O3 -fomit-frame-pointer compiled version.  Your results will
 * depend on how large of a buffer is used for z_stream.next_in & next_out
 * (8K-32K worked best for my 256K cpu cache) and how much overhead there is in
 * stream processing I/O and crc32/addler32.  In my case, this routine used
 * 70% of the cpu time and crc32 used 20%.
 *
 * I am confident that this version will work in the general case, but I have
 * not tested a wide variety of datasets or a wide variety of platforms.
 *
 * Jan-24-2003 -- Added -DUSE_MMX define for slightly faster inflating.
 * It should be a runtime flag instead of compile time flag...
 *
 * Jan-26-2003 -- Added runtime check for MMX support with cpuid instruction.
 * With -DUSE_MMX, only MMX code is compiled.  With -DNO_MMX, only non-MMX code
 * is compiled.  Without either option, runtime detection is enabled.  Runtime
 * detection should work on all modern cpus and the recomended algorithm (flip
 * ID bit on eflags and then use the cpuid instruction) is used in many
 * multimedia applications.  Tested under win2k with gcc-2.95 and gas-2.12
 * distributed with cygwin3.  Compiling with gcc-2.95 -c inffast.S -o
 * inffast.obj generates a COFF object which can then be linked with MSVC++
 * compiled code.  Tested under FreeBSD 4.7 with gcc-2.95.
 *
 * Jan-28-2003 -- Tested Athlon XP... MMX mode is slower than no MMX (and
 * slower than compiler generated code).  Adjusted cpuid check to use the MMX
 * code only for Pentiums < P4 until I have more data on the P4.  Speed
 * improvment is only about 15% on the Athlon when compared with code generated
 * with MSVC++.  Not sure yet, but I think the P4 will also be slower using the
 * MMX mode because many of it's x86 ALU instructions execute in .5 cycles and
 * have less latency than MMX ops.  Added code to buffer the last 11 bytes of
 * the input stream since the MMX code grabs bits in chunks of 32, which
 * differs from the inffast.c algorithm.  I don't think there would have been
 * read overruns where a page boundary was crossed (a segfault), but there
 * could have been overruns when next_in ends on unaligned memory (unintialized
 * memory read).
 *
 * Mar-13-2003 -- P4 MMX is slightly slower than P4 NO_MMX.  I created a C
 * version of the non-MMX code so that it doesn't depend on zstrm and zstate
 * structure offsets which are hard coded in this file.  This was last tested
 * with zlib-1.2.0 which is currently in beta testing, newer versions of this
 * and inffas86.c can be found at http://www.eetbeetee.com/zlib/ and
 * http://www.charm.net/~christop/zlib/

 * 2005 - Adaptation to Microsoft C Compiler for AMD64 by Gilles Vollant
 *
 * inffas8664.c call function inffas8664fnc in inffasx64.asm
 *  inffasx64.asm is automatically convert from AMD64 portion of inffas86.c
 *
 * Dec-29-2003 -- I added AMD64 inflate asm support.  This version is also
 * slightly quicker on x86 systems because, instead of using rep movsb to copy
 * data, it uses rep movsw, which moves data in 2-byte chunks instead of single
 * bytes.  I've tested the AMD64 code on a Fedora Core 1 + the x86_64 updates
 * from http://fedora.linux.duke.edu/fc1_x86_64
 * which is running on an Athlon 64 3000+ / Gigabyte GA-K8VT800M system with
 * 1GB ram.  The 64-bit version is about 4% faster than the 32-bit version,
 * when decompressing mozilla-source-1.3.tar.gz.
 *
 * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
 * the gcc -S output of zlib-1.2.0/inffast.c.  Zlib-1.2.0 is in beta release at
 * the moment.  I have successfully compiled and tested this code with gcc2.96,
 * gcc3.2, icc5.0, msvc6.0.  It is very close to the speed of inffast.S
 * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
 * enabled.  I will attempt to merge the MMX code into this version.  Newer
 * versions of this and inffast.S can be found at
 * http://www.eetbeetee.com/zlib/ and http://www.charm.net/~christop/zlib/

/* Mark Adler's comments from inffast.c: */

/*
   Decode literal, length, and distance codes and write out the resulting
   literal and match bytes until either not enough input or output is
   available, an end-of-block is encountered, or a data error is encountered.
   When large enough input and output buffers are supplied to inflate(), for
   example, a 16K input buffer and a 64K output buffer, more than 95% of the
   inflate execution time is spent in this routine.

   Entry assumptions:

        state->mode == LEN
        strm->avail_in >= 6
        strm->avail_out >= 258
        start >= strm->avail_out
        state->bits < 8

   On return, state->mode is one of:

        LEN -- ran out of enough output space or enough available input
        TYPE -- reached end of block code, inflate() to interpret next block
        BAD -- error in block data

   Notes:

    - The maximum input bits used by a length/distance pair is 15 bits for the
      length code, 5 bits for the length extra, 15 bits for the distance code,
      and 13 bits for the distance extra.  This totals 48 bits, or six bytes.
      Therefore if strm->avail_in >= 6, then there is enough input to avoid
      checking for available input while decoding.

    - The maximum bytes that a single length/distance pair can output is 258
      bytes, which is the maximum length that can be coded.  inflate_fast()
      requires strm->avail_out >= 258 for each loop to avoid checking for
      output space.

Summary
-------
This directory contains ASM implementations of the functions
longest_match() and inflate_fast(), for 64 bits x86 (both AMD64 and Intel EM64t),
for use with Microsoft Macro Assembler (x64) for AMD64 and Microsoft C++ 64 bits.

gvmat64.asm is written by Gilles Vollant (2005), by using Brian Raiter 686/32 bits
   assembly optimized version from Jean-loup Gailly original longest_match function

inffasx64.asm and inffas8664.c were written by Chris Anderson, by optimizing
   original function from Mark Adler

Use instructions
----------------
Assemble the .asm files using MASM and put the object files into the zlib source
directory.  You can also get object files here:

     http://www.winimage.com/zLibDll/zlib124_masm_obj.zip

define ASMV and ASMINF in your project. Include inffas8664.c in your source tree,
and inffasx64.obj and gvmat64.obj as object to link.


Build instructions
------------------
run bld_64.bat with Microsoft Macro Assembler (x64) for AMD64 (ml64.exe)

ml64.exe is given with Visual Studio 2005, Windows 2003 server DDK

You can get Windows 2003 server DDK with ml64 and cl for AMD64 from
  http://www.microsoft.com/whdc/devtools/ddk/default.mspx for low price)

; * Mar-13-2003 -- Most of this is derived from inffast.S which is derived from
; * the gcc -S output of zlib-1.2.0/inffast.c.  Zlib-1.2.0 is in beta release at
; * the moment.  I have successfully compiled and tested this code with gcc2.96,
; * gcc3.2, icc5.0, msvc6.0.  It is very close to the speed of inffast.S
; * compiled with gcc -DNO_MMX, but inffast.S is still faster on the P3 with MMX
; * enabled.  I will attempt to merge the MMX code into this version.  Newer
; * versions of this and inffast.S can be found at
; * http://www.eetbeetee.com/zlib/ and http://www.charm.net/~christop/zlib/

; match686.asm -- Asm portion of the optimized longest_match for 32 bits x86
; Copyright (C) 1995-1996 Jean-loup Gailly, Brian Raiter and Gilles Vollant.
; File written by Gilles Vollant, by converting match686.S from Brian Raiter
; for MASM. This is as assembly version of longest_match
;  from Jean-loup Gailly in deflate.c
;

;
; this file contain two implementation of longest_match
;
;  this longest_match was written by Brian raiter (1998), optimized for Pentium Pro
;   (and the faster known version of match_init on modern Core 2 Duo and AMD Phenom)
;
;  for using an assembly version of longest_match, you need define ASMV in project
;
;    compile the asm file running
;           ml /coff /Zi /c /Flmatch686.lst match686.asm
;    and do not include match686.obj in your project
;
; note: contrib of zLib 1.2.3 and earlier contained both a deprecated version for
;  Pentium (prior Pentium Pro) and this version for Pentium Pro and modern processor
;  with autoselect (with cpu detection code)
;  if you want support the old pentium optimization, you can still use these version
;
; this file is not optimized for old pentium, but it compatible with all x86 32 bits
; processor (starting 80386)
;
;
; see below : zlib1222add must be adjuster if you use a zlib version < 1.2.2.2

Then you can call puff() to decompress a deflate stream that is in memory in
its entirety at source, to a sufficiently sized block of memory for the
decompressed data at dest.  puff() is the only external symbol in puff.c  The
only C library functions that puff.c needs are setjmp() and longjmp(), which
are used to simplify error checking in the code to improve readabilty.  puff.c
are used to simplify error checking in the code to improve readability.  puff.c
does no memory allocation, and uses less than 2K bytes off of the stack.

If destlen is not enough space for the uncompressed data, then inflate will
return an error without writing more than destlen bytes.  Note that this means
that in order to decompress the deflate data successfully, you need to know
the size of the uncompressed data ahead of time.

 *                      - Simplify offs[] index in construct()
 *                      - Add input size and checking, using longjmp() to
 *                        maintain easy readability
 *                      - Use short data type for large arrays
 *                      - Use pointers instead of long to specify source and
 *                        destination sizes to avoid arbitrary 4 GB limits
 * 1.2  17 Mar 2002     - Add faster version of decode(), doubles speed (!),
 *                        but leave simple version for readabilty
 *                        but leave simple version for readability
 *                      - Make sure invalid distances detected if pointers
 *                        are 16 bits
 *                      - Fix fixed codes table error
 *                      - Provide a scanning mode for determining size of
 *                        uncompressed data
 * 1.3  20 Mar 2002     - Go back to lengths for puff() parameters [Gailly]

 * - If there are only literal codes and no lengths, then there are no distance
 *   codes.  This is represented by one distance code with zero bits.
 *
 * - The list of up to 286 length/literal lengths and up to 30 distance lengths
 *   are themselves compressed using Huffman codes and run-length encoding.  In
 *   the list of code lengths, a 0 symbol means no code, a 1..15 symbol means
 *   that length, and the symbols 16, 17, and 18 are run-length instructions.
 *   Each of 16, 17, and 18 are follwed by extra bits to define the length of
 *   Each of 16, 17, and 18 are followed by extra bits to define the length of
 *   the run.  16 copies the last length 3 to 6 times.  17 represents 3 to 10
 *   zero lengths, and 18 represents 11 to 138 zero lengths.  Unused symbols
 *   are common, hence the special coding for zero lengths.
 *
 * - The symbols for 0..18 are Huffman coded, and so that code must be
 *   described first.  This is simply a sequence of up to 19 three-bit values
 *   representing no code (0) or the code length for that symbol (1..7).

Building instructions for the DLL versions of Zlib 1.2.11
Building instructions for the DLL versions of Zlib 1.2.13
========================================================

This directory contains projects that build zlib and minizip using
Microsoft Visual C++ 9.0/10.0.

You don't need to build these projects yourself. You can download the
binaries from:
  http://www.winimage.com/zLibDll

More information can be found at this site.





Build instructions for Visual Studio 2008 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Compile assembly code (with Visual Studio Command Prompt) by running:
   bld_ml64.bat (in contrib\masmx64)
   bld_ml32.bat (in contrib\masmx86)
- Open contrib\vstudio\vc9\zlibvc.sln with Microsoft Visual C++ 2008
- Or run: vcbuild /rebuild contrib\vstudio\vc9\zlibvc.sln "Release|Win32"

Build instructions for Visual Studio 2010 (32 bits or 64 bits)
--------------------------------------------------------------
- Decompress current zlib, including all contrib/* files
- Open contrib\vstudio\vc10\zlibvc.sln with Microsoft Visual C++ 2010

  A CRC of a message is computed on N braids of words in the message, where
  each word consists of W bytes (4 or 8). If N is 3, for example, then three
  running sparse CRCs are calculated respectively on each braid, at these
  indices in the array of words: 0, 3, 6, ..., 1, 4, 7, ..., and 2, 5, 8, ...
  This is done starting at a word boundary, and continues until as many blocks
  of N * W bytes as are available have been processed. The results are combined
  into a single CRC at the end. For this code, N must be in the range 1..6 and
  W must be 4 or 8. The upper limit on N can be increased if desired by adding
  more #if blocks, extending the patterns apparent in the code. In addition,
  crc32.h would need to be regenerated, if the maximum N value is increased.

  N and W are chosen empirically by benchmarking the execution time on a given

  Lake i7, AMD Ryzen 7, ARM Cortex-A57, Sparc64-VII, PowerPC POWER9, and MIPS64
  Octeon II processors. The Intel, AMD, and ARM processors were all fastest
  with N=5, W=8. The Sparc, PowerPC, and MIPS64 were all fastest at N=5, W=4.
  They were all tested with either gcc or clang, all using the -O3 optimization
  level. Your mileage may vary.

  Generate tables for a byte-wise 32-bit CRC calculation on the polynomial:

  Polynomials over GF(2) are represented in binary, one bit per coefficient,
  with the lowest powers in the most significant bit.  Then adding polynomials
  with the lowest powers in the most significant bit. Then adding polynomials
  is just exclusive-or, and multiplying a polynomial by x is a right shift by
  one.  If we call the above polynomial p, and represent a byte as the
  one. If we call the above polynomial p, and represent a byte as the
  polynomial q, also with the lowest power in the most significant bit (so the
  byte 0xb1 is the polynomial x^7+x^3+x+1), then the CRC is (q*x^32) mod p,
  byte 0xb1 is the polynomial x^7+x^3+x^2+1), then the CRC is (q*x^32) mod p,
  where a mod b means the remainder after dividing a by b.

  This calculation is done using the shift-register method of multiplying and
  taking the remainder.  The register is initialized to zero, and for each
  taking the remainder. The register is initialized to zero, and for each
  incoming bit, x^32 is added mod p to the register if the bit is a one (where
  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by
  x (which is shifting right by one and adding x^32 mod p if the bit shifted
  out is a one).  We start with the highest power (least significant bit) of
  q and repeat for all eight bits of q.
  x^32 mod p is p+x^32 = x^26+...+1), and the register is multiplied mod p by x
  (which is shifting right by one and adding x^32 mod p if the bit shifted out
  is a one). We start with the highest power (least significant bit) of q and
  repeat for all eight bits of q.

  The first table is simply the CRC of all possible eight bit values.  This is
  all the information needed to generate CRCs on data a byte at a time for all
  combinations of CRC register values and incoming bytes.  The remaining tables
  The table is simply the CRC of all possible eight bit values. This is all the
  information needed to generate CRCs on data a byte at a time for all
  combinations of CRC register values and incoming bytes.
  allow for word-at-a-time CRC calculation for both big-endian and little-
  endian machines, where a word is four bytes.
